Skyscrapers

Want to learn how skyscrapers are built to scrape the sky? In this BrainPOP movie, Tim and Moby will teach you how these extra-tall buildings are constructed to balance the forces of gravity, tension, and compression! You’ll discover how skyscraper skeletons are formed out of a grid of beams and columns; why they’re made out of lightweight materials like steel; and how a skyscraper’s foundation distributes gravitational force over a wide area so that the building doesn’t collapse. So that’s why King Kong picked the Empire State Building instead of the Carnegie Deli!
